Hanger for blueprints or the like



Feb. 4, 1941. D. B. cAlN HANGER Fon BLUEPRINTS 0R THE LIKE Filed Oct. 7, 1939 PRDFILE Patented Feb. 4, 1941 iltii' sters-s PATENT FFECE 4 Claims.

This invention relates to a hanger for blueprints `or the like, and it is an object of the invention to provide a device of this kind which can be readily applied to the sheets whereby such sheets can be filed without folding or rolling and in a manner to obtain economy in the space required.

Another object of the invention is to provide a device of this kind which is provided with means whereby the same may be effectively locked to a supporting bar or can be readily removed when desired.

It is also an object of the invention to provide a device of this kind constructed in a manner to provide for tabulation and thus doing away with the use of separate tabs.

The invention consists in the details of ccnstruction and in the combination and arrangement of the several parts of my improved hanger for blueprints or the like whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be deinitely claimed.

In order that my invention may be the better understood, I Will now proceed to describe the same with reference to the accompanying drawing, wherein:

Figure 1 is a fragmentary View partly in section and partly in elevation illustrating hangers constructed in accordance with an embodiment l of my invention in Working position;

Figure 2 is an enlarged rear elevational view of a hanger as herein disclosed unapplied;

Figure 3 is an enlarged sectional view taken substantially on the line 3--3 of Figure 1, the hanger bar being in fragment and in elevation.

My improved hanger as herein disclosed comprises a rectangular sheet body I of a metal or bre possessing the requisite strength and rigidity. This sheet body I is elongated and relatively wide and preferably substantially rectangular in form. i

One end portion of the sheet body I is provided with an upwardly disposed extension or plate 2. This extension or plate 2 is relatively wide and has its periphery arcuate for an extent in excess of a semi-circle. A portion of the sheet body I to one side of the extension or plate 2 provides a surface of suiiicient area to allow the placement thereon of desired tabulations as indicated at 3. Overlying the rear face of the extension or plate (Cl. 2li- 154) 2 is a second plate 4 of a contour substantially the same as the extension or plate 2.

The plates 2 and E at the aXial center of their arcuate peripheries are tied or connected by a grommet 5. This grommet 5 provides a mountl5 ing for a disk 6 interposed between the plates 2 and 4 and which has serrated portions 'l in diametrically opposed relation which extend beyond the peripheries of the plates 2 and 4 to pro- Vide means whereby the disk t may be readily ro- 10 tated.

The upper portions of the plates 2 and l are provided with the transversely aligned slots 8 open at their outer ends and the upper portions of which `are adapted to be intersected by the hook 9 resulting from the bayonet slot it cut in the peripheral portion of the disk 6.

The plate 4 is provided with an extension or plate II which extends transversely across the end portion of the sheet body i immediately below the extension or plate 2, and this plate lI at substantially its junction with the plate 4 is secured tothe sheet body I by a staple i2 or the like whereby the plates l and li are maintained in desired position and against rotation about the grommet 5. The lower or free end portion of the plate Ii at substantially its transverse center has disposed therethrough a grommet I4, the opening of which aligns with the opening of a gromrnet I5 disposed thru the adjacent lower end portion of the sheet body l. As is clearly illustrated in the accompanying drawing, `the plates and 3a: each comprise a single elongated wide sheet.

The plate II below its fastening I2 is entirely free of the sheet body I whereby a marginal portion of a blueprint or kindred sheet may be readily inserted between the plate I I and the adjacent end portion of the sheet body I after which a suitable securing member I6, which may be as desired, is inserted through the grommets I4 and I5 and the portion of the sheet S inserted between the sheet body I and the plate I I.

Two or more of my improved hangers are preferably used in connection with a blueprint or kindred sheet S and the disk 6 of each of the hangers is rotated to open the slots I whereupon the hanger is engaged from below the bar I8 of a ling cabinet or the like, said bar being received within fthe slots I0. The disk 6 is then rotated to cause the hook 9 to extend across the top of the bar I8 and to close the upper open portions of the slots 8.

By the use of my improved hanger it is believed to be apparent that a blueprint or kindred sheet may be effectively supported or filed away without folding or rolling and in a manner whereby a print or sheet can be readily removed without disturbing other prints or sheets. It is also believed to be apparent that with the use of my improved hanger a print or sheet is suspended in a manner whereby the liability of the hangers becoming loose from the bars is substantially eliminated.

From the foregoing description it is thought to be obvious that a hanger for blueprints or the like constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modiiication without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myselfv to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice .except as hereinafter claimed.

I claim:

l. A hanger of the class described having a long and wide sheet body provided at one end portion with an upstanding plate, a second plate overlying the iirst plate, said second plate being continued by a third -plate extending across the adjacent end portion of the sheet body, the upper portions of the first two plates being provided with registering open slots, a member disposed through and connecting the rst two plates, a disk arranged between said rst two plates and rotatably supported upon the connecting member, the peripheral portion of the disk being provided with a hook to extend across and close the upper end portions of the slots in the first two plates, and means for securing the upper portion of the third plate to the sheet body whereby the major portion of said third plate is free from the sheet body to provide for insertion of the marginal portion of a sheet between the sheet body and the third plate.

2. A hanger of the class described having a long and wide sheet body provided at one end portion with an upstanding plate, a second plate overlying the rst plate, said second plate being continued by a third plate extending across the adjacent end portion of the sheet body, the upper portions of the rst two plates being provided with registering open slots, a member disposed through and connecting the rst two plates, a disk arranged between said rst two plates and rotatably supported upon the connecting member, the peripheral portion of the disk being provided with a hook to extend across and close the upper end portions of the slots in the first two plates, and means for securing the upper portion of the third plate to the sheet body whereby the major portion of said third plate is free from the sheet body to provide for insertion of the marginal portion of a sheet between the sheet body and the third plate, the disk having a portion .extending beyond the first two plates to provide means for rotating the disk.
